Two times the difference of 13
and a number is -4. Write an
equation representing this
situation and solve for the
number.

Answers

Answer 1

Answer:

Step-by-step explanation:

let number be x

CASE 1) when x>13

2(x-13) = 4

2x - 26 = 4

2x = 30

x = 15

CASE 2) when x<13

2(13 - x) = 4

26 - 2x  = 4

26 - 4 = 2x

22 = 2x

11 = x

You want to buy a new case for your iPhone. The case is $37 and the tax is 6%. WHAT IS THE TOTAL?

Answers

Answer:

$39.22

Step-by-step explanation:

The case costs $37. $37 is 100% of the price of the case.

The tax is 6% of the cost of the case. When you add 6% to 100% you get 106%.

The total price including tax is 106% of the price of the case.

106% of $37 = 1.06 * $37 = $39.22

Answer: $39.22

Oscar is landscaping his yard. He is putting mulch in the flower beds to help minimize weeds. He has 4 1/4 bags of mulch in his shed to use. Each bag of mulch will cover 70.8 ft.2. If Oscar uses all of the mulch that he has, how many sq. ft. will it cover? a 75.05 ft.2 b 282 ft.2 c 300.9 ft2 d 284 ft.2

Answers

Answer:

c) 300.9 ft²

Step-by-step explanation:

He has 4 1/4 bags of mulch in his shed to use. Each bag of mulch will cover 70.8 ft².

Hence:

1 bag of mulch = 70.8ft²

4 1/4 bags of mulch = x ft²

Cross Multiply

1 bag × x ft² = 4 1/4 × 70.8

x ft² = 4 1/4 × 70.8/1

x = 300.9 ft²

Option c is correct.

The measure of angle JKL can be represented using the expression 3x + 5.

Answers

Answer:

The measure of ∠JKL is 65°

Step-by-step explanation:

Consider the provided diagram.

We need to find the degree measure of ∠JKL.

It is given that ∠JKM=45° and ∠MKL=x°

Also it is given that the measure of angle JKL can be represented using the expression 3x + 5.

Thus ∠JKL=3x+5

From the figure it can be concluded that ∠JKL is equal to the sum of ∠JKM and ∠MKL

This can be written as:

∠JKL = ∠JKM+∠MKL

Substitute the respective values in the above equation.

3x+5 = 45+x

Subtract x and 5 from both the sides.

3x+5-x-5 = 45+x-x-5

2x = 40

x = 20

Thus, the measure of ∠MKL=20°

Substitute the value of x in ∠JKL = 3x+5.

∠JKL = 3(20)+5

∠JKL = 60+5

∠JKL = 65

Hence, the measure of ∠JKL is 65°

Tyler bought a jacket regularly priced $35.00.
With a 30% markdown and a sales tax of 6%, approximately what is the cost of Tyler's jacket?

Answers

Answer:

$25.97

Step-by-step explanation:

You want to find 70% of $35.00 because there is a 30% markdown meaning 70% of the original price. 70% is the same as 7/10.

to get the price after markdown multiply $35.00 by 7/10 which equals $24.5

Multiply $24.5 by .06 to get the sales tax which is $1.47

So the sales tax is $1.47 and the price after markdown is $24.5 so take the sum of both. $1.47 + $24.5 = $25.97

The cost of Tyler's jacket is $23.03.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Tyler bought a jacket regularly priced $35.00.

With a 30% markdown, the cost of jacket is

30% of 35

= 30/100 ×35

= 0.3×35

= 10.5

So, the cost of jacket is 35-10.5=$24.5

Now, sales tax on $24.5

That is, 6% of $24.5

= 6/100 ×24.5

= 0.06×24.5

= 1.47

Cost of jacket is 24.5-1.47

= $23.03

Therefore, the cost of Tyler's jacket is $23.03.

Suppose Sine (x) = negative three-fifths and cos(x) < 0. What the value of cos(2x)?

Answers

Answer:

[tex]-\frac{7}{25}[/tex]

Step-by-step explanation:

Value of given trigonometric ratio is equals to  [tex]cos (2x) = \frac{7}{25}[/tex].

What is trigonometric ratio?

" Trigonometric ratio is defined as in the right triangle the ratio which represents the relation between sides of a triangle with acute angle of a triangle."

Identity used

[tex]sin^{2} x +cos^{2} x =1\\ \\cos (2x) = cos^{2} x - sin^{2} x[/tex]

According to the question,

Given value of trigonometric ratio,

[tex]sin x = \frac{-3}{5} \\\\cosx < 0[/tex]

Substitute the value of [tex]sin x[/tex] in the above identity of trigonometric ratio,

[tex](\frac{-3}{5} )^{2} + cos^{2} x=1\\\\\implies cos^{2}x = 1- \frac{9}{25}\\ \\\implies cos x = \sqrt{\frac{16}{25} } \\\\\implies cos x = \frac{-4}{5} , cos x < 0[/tex]

Substitute the value of [tex]sin x[/tex] and [tex]cos x[/tex]  the trigonometric identity ,

[tex]cos (2x) =( \frac{-4}{5})^{2} - ( \frac{-3}{5})^{2}\\\\\implies cos (2x) = \frac{16}{25}- \frac{9}{25} \\\\\implies cos (2x) = \frac{7}{25}[/tex]

Hence ,  value of given trigonometric ratio is equals to  [tex]cos (2x) = \frac{7}{25}[/tex].

Use square roots to solve the equation x2 = –64 over the complex numbers. Select any solutions that apply.
A. 8i
B. –8
C. –8i2
D. –8i

Answers

Answer:

Options A and D are correct

Step-by-step explanation:

Here, we want to find the square root of the negative number;

x^2 = -64

x^2 = 64 * -1

x= √64 * √-1

Mathematically we can write the √-1 as i

X = √64 * i

Square root of 64 is plus or minus 8

so x = -8i or 8i

The solutions of an equation are the true values of the equation.

The expression that represents the solution(s) of [tex]\mathbf{8i}[/tex] is [tex]\mathbf{-8i}[/tex]

The equation is given as:

[tex]\mathbf{x^2 = -64}[/tex]

Take square roots of both sides

[tex]\mathbf{x = \pm\sqrt{-64}}[/tex]

Expand

[tex]\mathbf{x = \pm(\sqrt{64} \times \sqrt{-1})}[/tex]

[tex]\mathbf{x = \pm(8 \times \sqrt{-1})}[/tex]

In complex numbers,

[tex]\mathbf{ \sqrt{-1} = i}[/tex]

So, we have:

[tex]\mathbf{x = \pm(8 \times i)}[/tex]

[tex]\mathbf{x = \pm8i}[/tex]

Split

[tex]\mathbf{x = 8i\ or -8i}[/tex]

So, the expression that represents the solution(s) of [tex]\mathbf{8i}[/tex] is [tex]\mathbf{-8i}[/tex]

Xander goes to the movies with his soccer team. Each team member buys a ticket and two

boxes of popcorn. There are 13 team members.

Let t represent the cost of a ticket and p represent the cost of a box of popcorn.

a) Write two different expressions that represent the total amount the team spent.

b) Explain how each expression describes the situation in a different way.

Answers

Given that, the cost of a ticket = t and

cost of a box of popcorn =  p.

Total members in the team = 13

As each team member buys 1 ticket and 2  boxes of popcorn, so, the amount spent by one member, [tex]C_1 = t+2p[/tex]

So, the total amount that the team spent [tex]= 13C_1[/tex]

(a) So, the first expression, representing the total amount spent by the team, is

[tex]13\times (t+2p)\cdots(i)[/tex]

On simplification, the second expression, representing the total amount spent by the team, is

[tex]13\timest + 13\times (2p)[/tex]

[tex]=13t+26p\cdots(ii)[/tex]

(b) The expression from the equation (i) represent the total amount spent as 13 times the expenses of one member, while equation (ii) is the sum of two terms where the first term, 13t, represents the total amount spent for buying the ticket and the second term, 26p, represents the total amount spent for buying popcorn

Write the number as a power of 5. 125^3

Answers

Answer:

5^9

Step-by-step explanation:

125=5*5*5

125^3=125*125*125

125*125*125=3*(5*5*5)

the answer 5^9

The number as a power of 5 which is obtained by the number 125^3 using the power rule and simplifying is 5⁹.

What is the power rule?

The power rule states that, when the term is raised with a power which is again raised by another power, then this can be simply written as one power by multiplying both the power.

It has to write the number 125³ as a power of 5. Let the resultant number as a power of 5 is n. Thus,

[tex]n=125^3[/tex]

Rewrite the number with multiples of 125.

[tex]n=(5\times5\times5)^3\\n=(5^3)^3[/tex]

By the power rule, the above expression can be rewritten as,

[tex]n=(5)^{3\times3}\\n=(5)^{9}\\n=5^9[/tex]

Thus, the number as a power of 5 which is obtained by the number 125^3 using the power rule and simplifying is 5⁹.
